Patent GB-668304-A (GB)
Title: Tool for the treatment of woven surfaces
IPC: D06C11/00
Filed: 1949-03-01
Abstract: 668,304. Abrasive hand tools for treating fabrics. DIEBOLD, F. March 1, 1949 [March 5, 1948], No. 5502/49. Classes 19 and 60. A hand tool for treating fabric surfaces has elements 5 each individually and flexibly connected to a support 6 and provided with at least one sharp edge having a hardness greater than 7 in Mohs' scale, means being provided to prevent contact between the edges of adjacent elements during normal operation. The means consists either in providing pads of natural raw rubber, plastosyn or other synthetic material at the free ends of the tubular and elastic connecting members 12 or in placing the edges only at the tips of the elements which then act as guards. When a number of cutting edges 9, which may be of natural or synthetic diamond, are provided they may be arranged to lie on a cylindrical or other curved surface. The members 12 limit the action of the cutting edges on the surface to be treated and hence avoid damage to the latter. The Specification as open to inspection under Sect. 91, describes a construction which omits the means for preventing contact between the edges of adjacent elements and also one in which the connecting members are secured in a spokelike manner to a rotary support. This subjectmatter does not appear in the Specification as accepted.

Abstract: 271,575. Davies, J: Feb. 27, 1926. Spray and blowpipe burners.-In a liquid fuel, gas, or like burner of the type in which air is discharged in a diverging annular stream from a central passage A', fuel in a convergent annular stream from the second intermediate passage B<1>, and air from a third or outer passage C<1>, means are provided for causing the media .from one, two, or all three of the passages to rotate. These means may consist of helical ways 2, 3 in the central and intermediate passages and helical vanes 4 in the outer passage. The burner may consist of a central pipe A, a tube B and a sleeve C arranged concentrically and spaced from the furnace opening E. The sleeve C is provided with a damper 5 and. fitted at its rear end with a cap D which carries a fuel admission chamber B<3> and a reservoir B<2> communicating with the annular space between the tube B and pipe A. The pipe A extends through a stuffing box 7 at the rear of the chamber B<3>. The fuel may be supplied by gravitation at a pressure of from 5 to 6 feet head and the air by means of a power-driven fan at a pressure of about 1/3 lb. per square inch.

[Also in Group XXXV] In Fig. 2 a potentiometer P1 is set manually to correspond with the desired angle of elevation of the flight path of an aircraft and this angle is maintained by steering the aircraft manually in accordance with the indications of a pointer type indicator instrument 102. A D.C. signal obtained from potentiometer P1 is applied to a modulator M1 the A.C. output of which is combined with an A.C. signal obtained from the pitch pick-off of a gyro-vertical G1 and an A.C. signal from a pick-off 22 associated with a bellows 20. Bellows 20 is altitude responsive and has one end adjusted by a motor 19 computing altitude by integrating a voltage dependent on the setting of potentiometer P1 and the setting of a potentiometer P3 adjusted in accordance with airspeed. The resultant signal, which is thus dependent on the pilot's setting of potentiometer P1, the pitch angle of the aircraft and the difference between the actual height of the aircraft and its computed height is applied to an A.C. amplifier A1 which controls indicator 102 through a demodulator 104.

Filed: 1955-03-01
Abstract: 827,151. Purifying gases. GAS COUNCIL. Feb. 29, 1956 [March 1, 1955], No. 6078/55. Class 55 (2). In a process for removing H 2 S from gases such as coal gas the gas is washed with a solution of an organic dye base which will yield a readily oxidizable reduction product with H 2 S, the solution being regenerated by oxidation with air or oxygen. The dye base may be derived from a dye salt of the azine, triazine, oxazine or tri-phenylmethane classes, e.g. from methylene blue chloride. Methylene blue base may be made as follows :-To 100 c.c. of a 4% solution of methylene blue chloride in aniline, 0.5 c.c. concentrated ammonia solution is added. The solution is then reduced with H 2 S and extracted with an equal volume of water containing 5 c.c. concentrated ammonia solution followed by a second extraction, and if necessary further extractions, to remove all chloride ions. The solution is then aerated or oxygenated to yield a solution of methylene blue base. If during the process dye salts of sulphur oxy-acids are formed they may be converted back to the dye base by a treatment similar to the method of preparation described. Specification 827,152, [Group III], is referred to.
